The water restoration has been marked by many here as I see as "TV magic" but I found it available online: https://www.aliexpress.com/store/product......258.html and http://www.goshmagic.com/water-appear-from-empty-bottle.html but I'm still stuck as to how he introduced heat to the ramen. I get that he apparently has to use some sort of chemical to get the reaction but since he does eat them later I'm guessing it has to be something "non threatening". Any ideas?
